Peanut Butter Bars

I realized about 2hrs. before ballet practice that I was supposed to bring a treat for all the kids to share. I looked at my ingredients and looked online and found these gems. They're delicious and super easy. They taste a lot like Reese's peanut butter cups. Yum!

1 cup butter or margarine melted,
 2 cups graham cracker crumbs,
 2 cups confectioners' sugar,
 1 cup peanut butter,
1 1/2 cups semisweet chocolate chips,
4 tablespoons peanut butter

Directions

1. In a medium bowl, mix together the butter or margarine, graham cracker crumbs, confectioners' sugar, and 1 cup peanut butter until well blended. Press evenly into the bottom of an ungreased 9x13 inch pan.
2. In a metal bowl over simmering water, or in the microwave, melt the chocolate chips with the 4TBLS. peanut butter, stirring occasionally until smooth. Spread over the prepared crust. Refrigerate for at least one hour before cutting into squares.
